To all whom it may con-cern.'

Be it knownthat We, Jessen? Mnnmrr andi WILILIAM Hf Homes, citizens of the United States, and: residents of Hertford, in thel county of Hartford and State of Connecticut, haveinvented certain new and usefuli Improvements in Machines for Cutting Rings, oi? which the followingisa full, clear, and exact speciicatiom This invention relates tomwchines for cutting' circular packing' rings, or gaskets, as they are commonly termed-from cylindrical tubing;

The embodiment of this invention herein shown and described is a machine adapted# for cutting' ringl gaskets like those shown-l and describedy in U. S. Patent 826,104 of- July 17, 1906, having inclined edges and' intended for use in the closure joints of hermetieally sealed jars andl otherl receptacles.

is a plan View showing the cutter spindle sro carrying frame swung over to its inner posil tion, whichl may sometimes be convenient when cutting ringsfrom tubes of small diameter, especially when the angle of the cut requires the cutter spindle to occupy a more nearly parallel relation to the tube. Fig. 17 is a fragmentary plan view showing the relation of the'cutter to its direction of feed' and tothe angular line'of severance of the gasket rings.

The arrows placed' adjacent to the-several lines which indicate the plane in wl'iich the several different sectional views are taken show the direction| in whi'clr the respective sections are viewed- A brief statement of the purpose and functions of the machine willl befounduseful as a preface to the'detaled description of its construction and' mode' of operation.

The cylindricali tubes of rubber are stretched or otherwise mounted upona rotating mandrel. The cutter'i herein shown for the cutting of1 rubber' and similar material, has a thin sharp annular blade, and is rotated at a high rate of speed, by means of a cutter spindle mounted upon av cutter head supported by a carriage, by means of which the disk cutter is presented at a proper angle to the wall of the tube and is carried by an intermittent movement longitudinally of the tube, stopping at each intermission to allow the cutter to penetrate the wall of the tube at the required angle, and thus severing the successive rings as shown in Fig- 17. The alternate and intermittent feeding and cutting movements of the cutter, severing a ring for each forward step, are continued automatically the entire length of the tube, at.which point the feeding and cutting I movements are automatically stopped with the cutter in its outer osition, clear of the tube. At this point t e operator moves a reversing lever, throwing in the reversing mechanism which rapidly runs the carriage, with the cutter still in its outer position clearof the tube, back to the right hand end of the mandrel, in position for beginning a new cut. This reverse movementI is stopped automatically at the proper point. A The cut tube is removed, a new tube is substituted, and the operator, by means of another lever, starts forward the feeding and cutting mechanism again into operation, proceeding automatically as above described to the end of the tube, and so on. Interlocking devices are provided which serve to prevent interference of the several functions with each other; as for example, to lock the feeding mechanism out of operation during the return movement of the carriage, and vice versa.

The tube 2O of rubber or other suitable material from which the gaskets are to be cut is mounted upon a work-supporting spindle or mandrel 21 of suitable size, preferably larger .than the interior ofl the tube, the latter' being preferably stretched over the mandrel so as to hold itself thereto by constrictive action. To facilitate the ready removal and replacing of the tubes the mandrel preferably consists of a shell 22 removably mounted .upon an arbor 23 supported by the spindle 25 which is journaled in the spindlehead 26 resting'upon vthe bed 28, the spindle being driven bya driving pulley 29. The arbor 23 is also preferably made removable from the spindle to enable mandrels of different sizes and lengths to be used, suitable for various sizes of tubes. Any convenient means, as a nut 24, may bel employed for holding the shells upon the arbor. The shells 22 herein shown are assumed to be made of metal; and to avoid dulling the cuttery by contact with the surface of the shells the latter are provided with annular grooves 19 for receiving the edge of the cutter, as the latter cuts through the Wall of they tube in severing the .successive gaskets. Hence these grooves are arranged in a pitch or spacing agreeing with that -of the gaskets to be cut. Different shells provided with suitably spaced grooves are employed for cutting gaskets of differing width.

The cutting mechanism of the machine is mounted upon a carriage 56, mounted for sliding movement on the ways 58 and 59 of the bed 28, being moved upon the said ways longitudinally of the tube by means of any suitable actuator, such as the feed screw 60. The cutter head is mounted upon thecarriage and is composed of slides and swiveling parts for effecting the various operating movements and adjustments required for making gaskets of different size and angles. The rotary cutter 30 preferably employed in this machine is of a dished form provided with an annular cutting blade inclined to its axis of rotation and is shown in its preferred form in Fig. 17. For convenience in sharpening, renewal and replacing with other cutters of various diameters, it is detachably mounted upon the spindle 31. This spindle, rotated at a high rate of speed by means ofa belt on the pulley 32, is y carried in arms of the cutter head frame 33 hinged by pins 34 to plate 35 by means of which it may be swung' 180 degrees on a horizontal axis, from its position shown in Fig. 1 to that shown in Fig. 16, thus giving, in connection with the other adjustable parts of the cutter head, an extended range of adjustment to suit different sizes of tubes and differentangles of cut. The plate 35 swivels on the stud 37, secured in the upper slide 36, which in this respect serves as a base for the swiveling plate 35. This swiveling movement of the plate is to enable the inclined blade of the cutter to be adjusted into alinement with the direction of its cutting movement, through thel wall of the tube (Fig. 17). To enable this swiveling adjustment of the cutter` to be made accurately, without experiment, the plate 35 and its supporting slide-base 36 are provided with graduations 38. These graduations may be adapted to indicate in degrees the angle of inclination of the cutting blade, relative to itsvaxis of rotation. For practical considerations, however, the graduation is preferably made to show thecomplement of that angle; 01 in other words, the angle X indicated in Fig. 17 between the plane of rotation of the edge of the cutter; and the inner face of the inclined cutting blade,.that being the face which is preferably brought into coincidence with the line 39 of penetration through the wall of the tube and between the gaskets. The angle X shown in Fig. 17 is approximately 40 degrees. Hence for using that cutter the swivel plate 35 is set to 40 degrees as indicated by the graduation.

The slide 36 is mounted upon the slide 40, which is mounted upon the main slide 42. The latter slide is mounted upon the base 48 which is mounted upon the carriage 56 for swiveling movement about a vertical axis to enable the direction of cutting movement to be adjusted to the desired angle relative to the tube. The main slide 42 is reciprocated transversely to the axis by means to be described later, while the desired adjustments of the cutter relative to that axis are eected by the slides 36 and 40 and swiveling plate 35 above the slide 42. The slide 40 operated by the screw 43 adjusts the cutter mechanism in a direction coincidentwith the cutting vmovement to regulate the depth of out, while the slide 36 transversely mounted upon the slide 40 and operated by the screw 41 eects the adjustments ofthe cutter transversely to the direction of cutting movement, to enable the cutter to be readily adjusted to register with the grooves 19 of the shells.

To facilitate the adjustment of the cutter head upon itsA vertical aXis to bring the position of the main slide 42 to the angular position upon the carriage required for cutting the gasket at the required angle, the adjacent surfaces of the swivel base 48 and the swivel ring 55 are provided with graduations 50, by means of which the cutting mechanism may at once be set to the angle of the gasket to be made. When set to the desired angle the swivel base is clamped fast to the carriage bv means of the bolt 54 which tightens a portion of the swivel ring 55 upon the base.

From the fore oing it will be understood that the two swinging adjustments of the swivel base 48.upon the carriage and the swivel plate or bracket 35 upon the slide 36 are for entirely vdiderent purposes. The adjustment of the .swivel base 48 determines the direction of the reciprocating movement of the cutter, while the adjustment of the swivel plate 35 is used to bring the inclined blade of the cutter into coincidence with the line of cutting movement. Therefore the lower swiveling adjustment.` is employed only when changin the angle of the gasket to be cut, while tgfle upper .swiveling adjust'ment is employed only when the angle of the cutter is changed.

The driving mechanism for imparting reciprocating cutting movement to the cut` ter will now be described.

The main slide 42 is-\provided with a cam pin'or roll 45 preferably secured to the slide by means of a block 44 and engaging 'with the cam 46 carried by the vertical driving shaft 47, which is journaled concentrically with the vertical axis of swinging. movement of the swivel 48, preferably in a' bracket 49.

The cam shaft 47 is connected with the :splined driving yupon the bushing -or width of the gaskets to be cut.

shaft 65 by means of beveled gears 63 and 64 Fig. 6), the former being fixed to the sha t 47, while the latter, loosely mounted upon the shaft 65 is journaled in the bracket 49, by which the ear is carried along the shaft, with the sli ing movements of the carriage 56.

The rotary driving connection' between the gear 64 and the shaft 65 is made by neans of a flanged coupling 17 which is splined upon the shaft and is bolted to a fiange 18 of the gear, to permit of rotary adj ustment between that gear and the shaft, so as to adjust the cam 46 into proper time relation to the slide 42 and to readj ust it whenever changes are made in the angular position of that slide upon the carriage. For example, if the swivel base is swung 10 degrees the cam 46 must also be swung 10 degrees in the same direction to preserve the proper time relation between the feed mechanism and the cutting mechanism. To facilitate making this adjustment the abutting surfaces of the coupling 17 and the flange 18 of the gear are provided with graduations, preferably corresponding with the graduations 50 of the swivel base, so that the same angular adjustments may be easily made in both with certainty and accuracy. Therbolt holes, in the flange or-in the coupling are elongated to permit of their re quired relative movement.

The shaft 65 is journaled in the brackets 62 and 53 and has xed upon its left hand end the crank disk 68, from which driving movement is imparted to the feed screw 60, in proper time relationto the operationof the' cutting mechanism. The shaft 65 is driven during the cutting and feeding operations by the pulley 66, which is journaled 61 of the bracket- 62. Its driving connection with the shaft 65 is effected and controlled by clutch mechanism, which includes a pawl 67, mounted upon the pulley 66 and yieldingly held by a spring 3 into engagement with a shoulder 4 of the crank disk 68.

The crankv disk 68 is provided with a T- slot, to receive a slidin crank pin 71, to which is pivoted one end of the connecting ,rod 72, the other end being pivoted to the rockerarm 73, the upper portion of which carries the feed pawl 74 engaging the ratchet 75, which is fixed upon the feed shaft 81, which is journaled in the bed of the mach-ine, and is connected with the feed screw 60 by means of gears 134 and 135 (Figsp and 11). The ratchet 75 may be interchanged with others having a less or greater number of teeth, suited to the pitph T ie crank pin 71 is adjustable in its T-slot in the crank disk 68, to enable the stroke of the rocker arm to be regulated to suit the amount of advancing movement to be imparted through the feed shaft 81 to the feed screw 60. The ciank disk is provided with graduations 80 to `facilitate adjusting the crank pin, so as to impart the length of stroke required for the different Widths of gaskets. As previously explained, the feed or advancing movements of the feed screw and carriage are imparted While the cutter mechanism is at rest in its backward or retractive4 position, that mechanism performing its cutting operation upon the tube to sever a gasket during the intermission in the feeding movement, while the rocker arm 78 is being moved back to carry the feed pawl 74 into engaging relation to its succeeding tooth of the ratchet. These intermittent advancing movements of the carriage, alternating with the operations of the cutting mechanism, continue until the cutter reaches the end of the tube. Then the fe'eding and cutting operations are automatically stopped by knock-off devices which operate the clutch mechanism, raising the driving paWl 67 of the driving pulley 66 out of driving engagement with the crank disk 68. Provision is made for invariably stopping the feed mechanism in its retracted position, with the cutter clear of the tube, as shown in Fig. 17 and with the crank pin 71 and rocker arm 73 in their retracted positions, shown in Fig. 10.

The driving pawl 67 is journaled by means of the shaft 70 in the pulley 66 (Fig. 7 the other end of the shaft having fixed thereon the arm 90, which engages with the inclined surface 77 of the shipper cam 89, preferably by means of a roll 76 (Figs' 8 and 12). The shipper cam 89 ismounted loosely upon the bushing 61 upon which it is rotated with the pulley 66, by means of a driving arm or dog 10-1, appurtenant to the reversing gear' 114, which is fixed to or integral with the pulley 66. The object of rotating this shipper cam 89 with the pulley is to carry the inclined surface 77 in register with the roll 76.. But obviously this is not essential, since the inclination may extend entirely around the periphery of the cam 89, in which case no provision need be made for rotating it in register with the pawl arm 90. To lift the pawl out of driving engagement, the shipper cam 89 is moved toward the left, by means of the shipper 88 (Figs. 7, 12, 14 and 15), appurtenant to the shipper slide 87, which is mounted for'longitudinal sliding movement in the bracket 62; and is provided at its right hand end with the ship er rod 125 which extends lengthwise of t e bed of the Inachine, being supported in suitable brackets. A spring 5 extending between the bracket 6 and the adjustable nut 7 presses the shipper 88 toward the left, thereby tending to lift the latch 67 and disconnect it fromthe crank disk, the adjustment of the nut 7 enabling the tension of the spring 5to be varied to the required extent. At the right hand end of the machine or at any other convenient portion thereof a starting lever 124 engages With a collar 126, on the shipper rod 125, by means of which that rod and its connected shipper cam 89 are' moved to the right, to allow the driving pawl 67 to drop into engagement thereby starting the feed and cutting mechanisms into operation. The shipper and its rod are held in this running position by means of a latch 86 which is pivoted on the bracket 62, and is yieldingly held in the-position shown in Fig. 7 behind the locking piece131 of the slide 87 by means of the spring 180. The arm of the latch 86 is connected with a knock-'off rod 85, which extends the length of the machine, and is provided With an adjustable collar 84, with which the lower portion 83 of the bracket 49 collides, when the carriage reaches the prescribed limit of its advancing movement, the last portion of which operates through the rod 85 to Withdran7 the latch 86 from the shipper slide 87, thus releasing the latter and permitting the spring 5 to movey the shipper cam 89 to the left; and thus lift the driving pawl 67 out of driving engagement. The knock-ofi' rod 85 is also provided With handles 155 and 156 disposed at positions from which it ma be desirable to stop the machine by han The starting lever 124 is preferably provided With a spring 127, Which retracts the lever away from the collar 126, so that the spring 5 when released by the latch 86 does not have to overcome the inertia of the lever 12st; and therefore can operate the knock-off more quickly and uniformly.

To insure the positive stopping of the spline shaft with the cutter in its retracted position and positively prevent any movement of the cutter toward the tube during the return of the carriage, We have pro,

vided the latch 91 journaled in the bracket 62. When the knock-oil slide 87 is released and moves to the left it rides out from under the lower beveled face of the latch which by action of the spring 92 drops into engagement with the shoulder of the stop collar' 93 keyed upon the spline shaft. Having thus stop ed the advancin or feeding movement oi) may now be reversed to return it, preferably by e continuous and faster movement, to its initial position, ready for operation upon a new tube, by the reversing .mechanism which is best shown i F igs. 6, 7, 10, 11 and 12. The ratchet shaft" 81, which is connected withthe feed screw 60 by means of the gears 184, 135 (Figs. 6 and 12) has fixed near its left hand end the clutch disk 111, which is adapted to engage with the reversing clutch gear 107, which is mounted for rotary and endwise movement on the,

bushing 106. The rotary reversing movethe carriage, t e latter' ment of the gear 107 is imparted by the reversing gear 114, which is attached to or integral with the driving pulley 60, and connects with the reverse clutch gear 107 through the intermediate gear 115, which is mounted on the stud 113, thus rotating the gear 107 continuously in a direction suitable for reversing the movement of the feed screw 60 and its carriage 5G. In addition to its reversing clutch pins or dogs the gear 107 is provided with a pawl cam 108, which as the reversing clutch gear is moved to the left engages with the cam roll 100 appartenant to the pawl arm 110 fixed on the stud 112, which is journaled in the ratchet rocker 73, and has fixed upon its other end the ratchet pawl 711. The parts are so proportioned and arranged that the endwise movement of the pawl cam 108 first lifts the pawl 74 out of engagement with the teeth of the ratchet 75, and then by a continuing endwise movement comes into locking engagement with the clutch disk 111. While thus engaged the reversing movement is communicated to the carriage 5G, which is continued until the latter is returned to its initial position, whereupon the clutch gear 107 is moved to the right, back to the position shown in Fig. 11, thereby disconnecting it from the clutch disk 111 and stopping the reversing movement; and at thel same time dropping the ratchet. pawl 7-1 into engagement with its ratchet 75, thus restoring the connect-ion between the pawl and its ratchet ready for the next advancing movement of the carriage.

The end wise movement of the reversing clutch gear 107 is effected by means of the clutch lever 08, which istixed upon the shaft Sl journaled in the bracket 100, the upper forked end of'the arm engaging with the groove 105 of the reversing clutch gear 107. rl`hc opposite end of the shaft 99 has fixed upon it the reversing arm 97, which is connected b v means of the rod 101 with the reversing lever 91, which is pivotally mounted upon the bed and is provided with a spring 102 tending to hold the lever and its associated parts in their inoperative position shown in Figs. 8 and 11. The top of the lever 94 is moved to the left by the operator, to throw the reversing mechanism into operation; and is latched in its reversing position by means of the latch 120, mounted on the stud 121, and engaging with a suitable catch or shoulder 122 on the reversing lever 941. r1`he latch 120 is provided with a knock-ofi' rod 119, which extends lengthwise of the bed, supported in suitable brackets, and is provided with an adjustable collar 11S, with which a projecting arm 123 of the carriage collides, as the carriage approaches the end of itsl reversing movement, the latter portion of which operates by moving the collar 118 and its knock-oft' rod 119.to the right to lift the latch 120 and release the reversing lever therefrom, whereupon the latter is moved by the spring 102 to the position shown in Fig. 8, thus disconnecting the reversing clutch gear 107, and permitting the carriage to stop. The knock-oft rod is also preferably provided with a handie 157, by means of which the latch 120 may be tripped, so as tov enable the reversing movement to be stopped by hand at any desired position, in addition to and independently of the automatic stopping action at the end of its movement.

The machine is provided with interlocking and stop devices cooperating with the clutch mechanism of the machine to prevent improper operation of the machine, which, might otherwise occur through inadvertence or carelessness on the part of the operator. The clutch mechanism for effecting the forward and return movements of the carriage is interlocked by means of the lock arm 96 herein shown to be appurtenant to the re versing arm 97; and having a lockingprojection 95, which extends into the plane of movement of the stop block 9 appurtenant to the shipper slide 87 (Figs. 8, 12, 14 and 15). During the time that the shipper slide is drawn to the right to put the forward feed in operation, the portions of the stop block 9 9 overlie the projection 95 of the locking arm 96 and prevent the reversing mechanism from being moved far enough to throw the reversing gear 107 into clutch with the clutch disk 111, although the block 9 allows the reversing mechanism to be moved far enough to cause the pawl cam 108 to lift the pawl 74 out of driving engagement with its ratchet for apurpose to be later described. When, however, the shipper slide 87 is released from its latch 86 and is moved toward the left far enough to lift the driving pawl 67 out of forward driving engagement, the recessl() of the stop block is carried over the top projection 95, whereupon the reversing mechanism may be operated, the projection 05 entering the recess 10; and thereby locking the shipper slide 87 out of operation. Thus these interlocking devices serve to prevent the forward driving and the reverse driving mechanisms from being put in operation at the same time.

lt is found convenient, while adjusting the parts for operation, and particularly While adjusting the cutter to carry it to its proper depth, to operate the cutting mechanism of the critter' head without operating the feed mechanism, so that the cutter makes repeated cutting strokes, without advancing the carriage. To enable this to be done, in spite of the interlocking devices, and without impairing their utility, sufficient space is left between the stop block 9 and its coperating stop projection 95 of the stop arm 96, to allow the reversing lever to be moved toward the left far enough so that the pawl cam 111 will lift the ratchet pawl 74 out of engagement with its ratchet, without bringing` the reversing gear 107 and the clutch disk 108 into engagement with each other. In order to retain the parts in this position during the operation of setting the cutter, a. latch 12 is provided, which. is pivoted u on a fixed portion of the machine and is pre erably forked so as to extend on opposite sides of the reversing lever 94 when turned down. With the lever in this position, holding the feed pawl 74 out of operation, the'driving shaft may be started by operating the starting lever 124, thus causing the cutter slide 42 to be moved back and forth through its normal stroke, without operating the feed shaft.

It has been found to be advantageous to keep the rubber tube wet while being cut, and to accomplish this we have arranged a Water feed device consisting of a supporting post 140 clamped in the bracket 141 upon the back of the carriage, and on the upper end of this post rests the arm 142 to which is pivotally connected the yoke 143 having hinged therein by stud 145 the yoke ring 146 threading into the T 147. To this T is attached the hose 148. supplying water by gravity from a reservoir or from a pump. To the other outlet of the T 147 is attached the nozzle 150, adjustable through hinge of yoke ring 146 or stud of yoke 143 and arm 142 ,to any angle, so that the water may be applied directly upon the cutting line of cont-act, as shown in Fig. 9, either from above as shown in full lines, or from below, as shown in dot-and-dash lines. The entire water feed device is also adjustable vertically in the bracket 141 to provide for any size of tube being cut.

The consecutive operation of the machine as a. whole is as follows z-Power being applied toY the different driving pulleys and the rubber tube to be cut being in place upon the mandrel and the cutter properly adjusted to its cutting position, the operator, first observing that the reversing lever 94v is in its right hand or inactive position shown in Fig. 2, moves the starting lever 124 to the right, therefore dropping the driving pawl 67 into engagement, thus starting the cutting and feed mechanisms into operation. These continue in alternate operation until the end of the tube is' reached, whereupon the lower end 83 of the bracket strikes the knock-off collar 84, thereby withdrawing the latch 86 and allowing the shipper slide 87, its arm 88 and the cam 89 to be' moved to the left by the spring 5, thus unclutching the forward driving mechanism by liftingthe feed pawl 67 out of engagement and stopping the feed and cutting mechanisms. The movement of the shipper slide 87 to the left allows the stop latch 91 to engage with the stop collar 93, thus positively stopping the cutting mechanism in its retracted position, with the cutter clear of the tube, as shown in Fig. 17. The reversing arm 94 is then moved to the left, lifting the feed pawl 74 out of driving engagement with its ratchet 7 5, and clutching together the reversing gear 107 and the clutch disk 111, `which rotates the screw rapidly in a reverse direction, thus moving the carriage back to the other end of the tube. During this time the reversing lever is held in its reversing position by means of the latch 120. Arriving at the end of the return movement the carriage collides with the knock-off collar 118 carrying with it the rod 119 and thus lifting the latch 120 and releasing the reversing lever 94 which then, under the impulse of the spring 102, is moved with its associated clutch mechanism back to the position shown in Figs. 2 and 8, disconnecting the reversing gear 107 and dropping the feed pawl 7 4 back into engagement with its ratchet 75. The carriage having come to rest, the cut gaskets are removed preferably by removing the shell upon which they are mounted. The cut gaskets are replaced by a new tube. and the feeding and cutting mechanisms are again started by means of the starting lever 124, as before.

The above order of operations may be varied to suit dierent conditions. For example, it may be found advantageous to remove the gasket shell while the carriage and cutter are at the left hand end of their feeding or advancing movement, so as to give the operator time to remove the cut gaskets from the shell and replace them with a new tube while the carriage is being returned to its starting position.

`The size, form and inclination of cutter may and should be varied to suit different sizes of gaskets and different angles of cut, in order that they may be cut cleanly and coliform sufficiently well to the annular extension of the cut. For some purposes it may be found suicient or even preferable to use a non-rotating cutter, of a form suited to the cut to be made. The means for clamping. holding, or supporting the cutter should also be adapted by modification. if necessary, to suit the size or form or style of cutter employed.

Various other modifications may be made in the size.,A shape, position, and the direction of movement of the various parts of the machine, and equivalent mechanical devices may be substituted for effecting the desired movements. For example, the path of the cam 46 may be variedto alter the time of the cutting mechanism. In some cases crank mechanism may be substituted for cam mechanism and the movementsI characteristie of the crank may be modified in ways well known to those skilled in this art. In any other ways which will occur to mechanics familiar with this art, `the invention herein shown may be modified to suit different requirements or conditions.
